Dha phase 9 - 5 marla - advice needed

Can you please advise me about the expected rates of dha phase 9, 5 marla plot as per your knowledge and expert judgement.
If i spent 20 lacs now to buy a 5 marla file and then 3-4 lacs development charges later on then on possession (i expect it around 2025) what will be the price of my plot if it is on some average location. I guess it should be somewhere between 50-60 lacs. I know it is not possible to make a nice guess because 2025 is far far away however i just need your guess with available trend/information.

Also a guess about it's price after 5 years from now?

Around 50-lacs in 2025 (just a guess)

And what will be price of 10 marla in same price of dha 5 marla in awt ph 2 , nfc , lda city . State life ph 2 , and even a kanal in pechs islambad in 2025?
